A cryptocurrency faucet is a website or service that gives out small portions of coins in exchange for completing simple tasks or for user activity.

A QR code is a two-dimensional graphic image that encodes data and is read by a camera; in cryptocurrencies it is used to quickly transmit addresses and payment details.

Litecoin is one of the oldest altcoins, created as a faster and lighter alternative to Bitcoin and the originator of the use of the Scrypt algorithm.

Mining is the process of supporting the operation of a blockchain by solving computational tasks, for which participants receive a reward in coins. The issuance of many cryptocurrencies is based on it.

A microtransaction is a payment of a very small amount, often less than the minimum monetary unit. Such operations are unprofitable for traditional payment systems because of fees, while cryptocurrencies make them feasible.

Multisignature is a technology in which carrying out a transaction requires not one but several signatures with different private keys. It noticeably increases the security of storing crypto assets.

Ether (Ether, ETH) is the native cryptocurrency of the Ethereum blockchain platform, the second most important in the industry. In traders' jargon there are playful distortions of the name — "kefir," "efir," "zemfir" — but they always refer to one asset.

A client (Client) is a program that enables a user to interact with a blockchain network: transfers, balance checks, and data synchronization. The most familiar example of a client is a cryptocurrency wallet.

A coin (Coin) is a unit of cryptocurrency that runs on its own independent blockchain. This is exactly what distinguishes a coin from a token, and the word itself is often part of the names of many cryptocurrencies.

Cryptography is the science of methods for protecting information by means of encryption. It ensures confidentiality and data integrity and underlies the operation of all cryptocurrencies.
